WLD 222 - Pipe Welding 1 Basic
Credits: 3
2 Lecture Hours 2 Lab Hours
Prerequisites: WLD 201
Description
This course provides students with knowledge and skills to effectively begin basic techniques of uphill shielded metal-arc welding (SMAW) for pipe. Uphill welding is generally used on thick-wall pipe. Students will practice their basic skills on metal plates before transitioning to 6” diameter pipe. The American Society of Mechanical Engineers (ASME) and American Welding Society (AWS) code specifications will be followed.
Learning Outcomes
Upon successful completion of the course, the student will:
- Prepare a v-groove joint with open root.
- Demonstrate shielded metal-arc welding on beveled plates in 4 positions.
- Produce a shielded metal-arc weld on schedule 40 pipe in the 1G position.
- Make a shielded metal-arc weld on schedule 40 pipe in the 2G position.
- Produce a shielded metal-arc weld on schedule 40 pipe in the 5G position.
